For printing clear filament to any translucent color with a Fat chisel Sharpie marker. I also provided a Prusa I3 frame mount that allows swiveling. If you plan to use with other makes of printers, I can work with you to get a hinge pin system for it .
Clear plastics will result in semi transparent colors
While will produce Opaque colors.
For best results use brand name Sharpies as the will not dry out and last for a full roll if not more ! See photo
